I Specification of Letters Patent.

Patented May/22, 1906."

Application filed April 3,1905. Serial No. 253.675,

To all whom it may concern.-

Be it known that I, ALBERT H. OLMs'rnD, of Rochester, in the county ofMonroe and Stateof New York, have invented certain new and usefulImprovements in-Spools or, Reels; and I do hereby declare the. followingto him full, clear, and exact description of the same, reference beinghad to the accompanyforming a part of this specification, and to thereference-numerals marked thereon.

My present invention relates to s ools or reels for winding urposesgenerally, but particularly applica le for, use in type-writingandanalogous' machines wherein a carbon tape or ribbon is fed fromfonespool to anot er and then wound in the opposite direction; and it, has'for its object'to provide a simple attaching means for securing the endsof such tape or ribbon to the drum so disposed as not to disturb thecylindrical regularity'of the coil; and a further object of my inventionis tofasten the ribbon in such a manner that when totally unwound theend cannot become accident lly loosened by a ionof the feed, yet may beeasily detached and replaced by a new one after having served its periodof usefulness.

To these and other ends the invention consists in such im rovements andcombinations of parts as W1 be further more fully described, the novelfeatures being pointed out in the claims at the end of thespecification. In the drawings, Figure .1 is a side eleva-' tion of aspool embodying my invention.

section taken' transversely ofthe axis, and Fig. 4 is a section takenlongitudinally of'the axis, on the line mm ofFi 1, showing a portionSimilar reference-numerals in the several figures indicate similarparts.

Referring to the drawings, 1 indicates the flanges or guiding portionsof the spool, having the usual relnforcing-ribs 2 sta'm ed from theirsurfaces to aiford greater rigidity to the thin material from which theyare usually made and provided with central apertures 12, through whichproject the reduced ends of a tubular core .13, having the shoulders 14abutting the inner s aces, and said ends being '11 set or rivetedagainst the outer surfaces. his forms a firm and adequate bearing forthe rotation of the reel, es-

pecially when it is of greater length than the spindle upon which it ismounted, as is frequently the. case, and where the istering aperturesgenerally de for this function would be of litt ended upon e avail. The

drum or barrel 3 is provided at its ends with.

laterally-projecting ears 4, which enter correspondin l haped aperturesor slots 5 in the side anges and are clenched closely against the outersurface. 'It is preferably formed of a single strip of sheet materialrolled to a hollow cvlindrical form and the opposite regmeeting endsbent inwardly to form a dee'located without disturbing the continuity ofthe cylindrical surface. This latter embodies a transverse plate 7,having a series of teeth 8 upon one edge thereof and extensions 9 uponits ends correspondin to the ears 4 upon the drum and used in hiemanner, ex cepting that the slots 10, throu h which they project, are ofsufficient width to allow a slight rocking motion and also movement in aradial direction. The extensions 9 and the ears 4. as well are seated indepressions 11 stamped from the outer faces of the'side portions to lieflush therewith for the purpose of rendering suchfaces plane surfaceswithout projections of any kind to ofier obstruction when the reel isrotatably mounted on its pression 6, wherein the attaching means mayholder by means of the aperture 12.

Tov attach a ribbon, device maybe used, such of approximately. the samewidth, over whic the end .of the ribbon is folded and then thrustbeneath the plate 7 from the side opany suitable threading as a thinmetal str pv posite to that carrying the teeth 8 and then Withdrawn. Thesaid teeth are curved slightl and only their points rest in contact witht e periphery of the drum, so that they readily pierce the fabric,andtheir tendency is then to bind downwardly and lock against disengaement when the ribbon is drawn taut for furt er winding by reason thepoint of engagement is below the pivotal or rocking center, as .wi isintended-to 'd the ribbon in the direction of the teeth, as it therebyencircles the plate, and the greater art of the tensile strain isapplied uponthe lank edge rather than upon the teeth, in would be atendency to ri advantage is also exhibits from one reel to another, asis the case, the feeding-coil becomes or tear, and this when infrequently exhausted which latter case there;

of the fact that i 1 0o 11 be understood. It

and the strain falls directly upon the attached end, as shown in Fig. 3.

I claim as my invention- 1. In a reel, the combination with the endflanges and the drum, of a central bearing member comprising an integraltubular core lying within-the drum and forming a rigid connectionbetween the end flanges 2. In a reel, the combination with the endflanges having the central apertures and the hollow drum, of a bearingmember comprising an integral tubular core lying within the drum andsupported in 'the apertures in the end flanges and a positive connectionbetween the latter and the core.

3. In a reel, the combination with the end flanges having centralapertures and the hol- 1 low drum, of a bearing member comprising atubular core with its ends mounted in the apertures in the end flangesand having shoulders abutting the inner surfaces of the latter.

4. In a reel for tape or ribbon, the combination with the drum and theend flanges, of

a plate having pivotal connections with the plate lyin contiguous tosaid drum and secured to t e flanges and teeth on said plate I adaptedtopierce the end of a ribbon-in attaching it thereto.

7. Ina reel for tape or ribbon, the combination with 'end flanges and acylindrical drum having adepression therein, of a plate- .arrangedopposite the depression, its outer surface forming substantially acontinuation of the periphery of the drum, pivotal projections uponthe-ends of the plate lying in the plane t ereof, and bearing in the endflanges and teeth upon the plate for engaging a ribon. v 8. In a reelfor tape or ribbon, 'the combination with the drumand flanges of a platelying contiguous .to said drum and having pivotal pro ections at itsends supported in bearings in said flanges said bearings being. locatedin substantial roximity tothe drum, and means on said p ate forattaching a rib bon thereto.

9.i In a reel for tape or ribbon, the combiwithin tlie radius of thecylinder, pivot projections on said plate having bearings in theflanges, and means thereon for attaching a ribbon thereto. i

10. In a reel for tape or ribbon, the combination with the drum andflanges, of a flat plate lying contiguous to said drum'and having pivotaprojections at its ends mounted inbearings in saidflan es, said bearingsbeing 10 cater in substantia proximity to the drum, and teeth on saidplate adapted to pierce the end of a ribbon in attaching it thereto.

11. In-a reel for tape or ribbon, the combination with the drum having adepression therein, and the flanges, of a late opposite the depressionand so arrange that its outer surface forms a continuation of thesurface of the drum, pivot projections on said plate bearing in theflanges and ribbon-en aging portions on the plate for engaging a rib onin attaching it thereto ALBERT H.v OLMSTED.
